Just a few queries to the answers suggested here. If you can tell me how you got your answer, that'd be awesome and I can see where I stuffed up (or vice-versa, if it so happens)

5. B, his standards are better than his character (general answer is "A: no club has low enough standards for him")
6. C, Tolkien's experience in the army led to a disenchantment with reality (general answer is "A: let to a fascination with writing", though it then said he created stories "based upon his studies of mythology and folklore" so I thought he might be into writing already)
9. D, his novels have shaped the way in which people view fantasy stories (general answer is "C: he wrote fiction which appealed to both adults and children")
17. B 60 years because the marker "World", a rectangle, in Figure 1 showed a life expectancy of approximately 61 years (general answer "C: 64 years")
22. C more difficult to apply and more effective at reducing pain. (general answer is "D: more effective at reducing pain but less effective in reducing swelling" however, since Herbal extract 2 reduces swelling and the new recipe contains herbal extract 2 and recipe IV does not, it should be MORE effective in reducing swelling)
33. A 3J=2E as Y/5 = J/2 --> (J+E)/5 - J/2 = 0 --> 2J + 2E - 5J = 0 --> 2E - 3J = 0 --> 2E = 3J (general answer is "B: 3E=2J")
45. D oil as the medium is necessary to produce a green oil alteration. Query: the arrows from (1) point to both of the boxes in (2), so regardless of whether or not the copper plate was scratched, it can still have any of the patinas on it... (general answer "A: a scratched copper plate" which would be correct if the arrow thing was just me...)
53. D above 30 degrees it is possible for development to occur without growth, as from 36 to 38 degrees, development DOES occur without growth (general answer "B: development cannot occur without growth")
65. B flapper valve IV only (general answer "C: both III and IV")
Cheers,
Sam
